6 Channel differential input multifunctional USB DAQ

[faromarc]

Hey guys,

i'm looking for a multifunction DAQ like USB-6002 which i already have

https://www.ni.com/en-us/shop/model/usb-6002.html

but i need to measure 6 channels differential input.

Do you have any recommendation on a multifunctional DAQ?

Perhaps the USB-6210 will work for you.

If the budget allows it: Avoid multiplexing ! 

Have a look at the settletime error spec! 

You haven't told us about your signal sources , needed accuracy and needed bandwidth ..

The USB 6356  or 7845R (small FPGA, migth need more thinking 😉 ) ??

The USB-6210 seems perfect.

Thanks!

I have 6 Channels and for each channel another GND.

So i measure 6 channels differential. Where do i connect the wires at the Pinout of the USB-6210?

For AI0, AI8 is the negative side when configured as a differential channel.  AI1- = AI9, etc.

That is the reason why those channels are very close to each other in the device pinout's.
